Partial breakage of a tunneled dialysis catheter: An uncommon finding

Double pigtail catheter reduction for seriously displaced intravenous infusion port catheter: A case report

BACKGROUND

Implanted intravenous infusion port (TIAP) is mainly used for patients who need central venous infusion and poor peripheral vascular conditions. With the advantages of easy to carry, long maintenance cycle, few complications and excellent quality of life, it has been widely used in the fields of malignant tumor chemotherapy, parenteral nutrition support and repeated blood collection. Implanted intravenous infusion port (IVAP) dislocation can have significant complications if not recognised and reinstated immediately.

CASE SUMMARY

A 24-year-old man was treated with adjuvant chemotherapy for osteosarcoma. Severe displacement of IVAP catheter was found by chest X-ray examination. The IVAP cannot be used normally. Therefore, we conducted an emergency procedure to reset the catheter through double pigtail catheters, the operation was successful and the infusion port was restored.

CONCLUSION

When IVAP catheter displacement cannot be reset by conventional techniques, two pigtail catheters can be successfully used instead.

An unusual complication of prolonged tunneled cuffed hemodialysis catheter

A 57-year-old male patient visited our center owing to abnormal tunneled cuffed hemodialysis catheter (TC-HDC). He had been undergoing hemodialysis for 44 months. Hemodialysis was performed using a TC-HDC, which became dilatated between the hub and exit site 19 months after the initiation of hemodialysis. The first TC-HDC was exchanged using over the guidewire method. The second TC-HDC was maintained for 25 months after catheter exchange. However, the second TC-HDC was repeatedly dilatated 25 months later from the first catheter exchange. We re-exchanged the dilatated TC-HDC to the new TC-HDC using over the guidewire method. Our case presented general dilatation of both lumens without leakage. The portion of catheter dilatation was limited between the hub and exit site. The embedded segment of the catheter was preserved owing to encasement of the adjacent tissue. Our case showed that clinicians should inspect both exposed and embedded segments to prevent further catheter injury and exchange the catheter before the development of complications.

Removal of "ruptured" pulmonary artery infusion port catheter by pigtail catheter combined with gooseneck trap: A case report

BACKGROUND

Implanted intravenous infusion port (IVAP) is indicated for patients undergoing chemotherapy, total parenteral nutrition and long-term antibiotic treatment. Among their complications, the rupture and migration of the catheter of an IVAP via internal jugular vein represents a very rare but potentially severe condition.

CASE SUMMARY

A 43-year-old woman was identified with a spontaneous fracture and migration of catheter of an IVAP via right internal jugular vein after adjuvant chemotherapy for left breast cancer. A computed tomography showed the fractured catheter of the IVAP in the pulmonary artery. Therefore, we conducted an emergency procedure to remove the catheter fragment by a pigtail catheter combined with a gooseneck trap.

CONCLUSION

When the fractured catheter of an IVAP was detected, the special shape of the pigtail catheter in combination with the gooseneck trap successfully facilitated the removal of the dislodged catheter.
